1. Installation

1.4 Installation of Machine with Full-load Hydraulic Oil Usually, each machine is filled with a proper amount of hydraulic oil before leaving the factory and the motor is wired according to the required voltage. When the rocker head moves up after starting the motor, the rotation direction of pump is correct. The rocker head will not raise up if the motor polarity is incorrect. 1.5 Installation of Machine with No-load Hydraulic Oil If your machine was shipped without #46 hydraulic oil, because of transportation regulations, it’s necessary to carefully fill up the oil tank from the notch at side of oil cylinder according to the following procedures:

Fill up enough hydraulic oil until the oil reaches the position nearby the bottom of threaded hole under notch of to the maximum level.

Turn on the machine, observe if the pump rotates correctly according to the above mentioned procedures. Rotate the rocker head counterclockwise until rocker head stops and then head should rise to maximum stroke.

Place a block of wood at least 1" thick or other hard materials between the cutting table and head, start the machine. Push both switches on/off simultanously for several minutes. This procedure aims to remove air from relevant pipelines of oil cylinder.

Remove previously used spacer, make sure there is nothing on cutting table, slowly rotate the adjustment disc clockwise until rocker goes down to a position that is about 3/8" away from the table surface. Then, check the oil amount in oil cylinder and refill with hydraulic oil as necessary. This way the necessary oil amount will be ensured in oil cylinder.

A-922/925/928 Instruction Manual 2. Usage2.2 Cutting This machine has automatic stroke limitation function. Operators may use cutting dies with different heights without any adjustment, so operation procedure can be simplified as follows: Lay your leather or other materials on the cutting table, then place your die in the

correct place.

After properly adjusting the stroke (recommended stroke:1/4" to 3/8") with adjustment disc, adjust the potentiometer to the proper cutting force and then simultaneously press the operation buttons on left and right handles. Release after the parts are cut and head begins to ascend back to the home position.

Operation Instruction of Three-key Handle (Special Order) After adjusting the stroke (recommended stroke:1/4-3/8") with adjustment disc,

simultaneously press the button on right handle and the most suitable of the three keys on left handle. According sharpness of cutting die, adjust the pressure divider working with #1 and #3 keys when necessary (see 2.1). In this way, optimum cutting effect can be achieved and damage to the cutting table can be minimized.

Note: Make sure the swing arm head fully covers your cutting die before pressing the operation buttons. (Fig. 6).

2.3 Danger of Leaving Other Objects on Table Surface When Shutting Down Machine.

About forty seconds after powering off the machine,

the rocker head will begins to descend slowly. (Fig. 7).

2.4 Special Cutting “Special cutting” is used with small or thinner wall cutting dies.

Fig.8

Usage: 1) Dial selection switch shown in the diagram to the position of “special cutting” (Fig.8).If only two single-key handles are installed on the machine: 2) Reset potentiometer, placing the die and adjust the regulating handle of rocker head

to determine proper height of rocker head. 3) Keep the height of rocker head unchanged and gradually adjust potentiometer

until reaching required cutting effect.

If three-key handle is installed on the machine: 4) Reset two potentiometers, place the die and adjust the regulating handle of rocker

head to determine proper height of rocker head. 5) Keep height of rocker head unchanged and gradually adjust potentiometer of #1 key

until #1 key reaches the required cutting effect. Keep the height of rocker head unchanged, put a cutting die with different wall heigth and gradually adjust the potentiometer of key #3 until the #3 key reaches required cutting effect.

6) When changing the height of rocker head or the size of cutting die, it’s necessary to readjust the potentiometer to obtain the required cutting effect.

7) Turn the dial selection switch to “standard cutting” position and the machine will automatically position at stroke terminus. In other words, in mode of “standard cutting”, after the height of rocker head is changed, the pressure of the machine will stay unchanged. It is unnecessary to readjust potentiometer.

Remarks: 8) Under standard configuration of our Clicker machines, the cutting dies used for cutting must

be at least 5/8" in wall heights9) DO NOT OPERATE YOUR MACHINE without block of wood or cutting die less than

1/2" under the cutting head. Damage to the machine WILL result!10) Normal cutting is available only when the distance or total thickness of aluminum plate,

work to be cut and cutting die between rocker head and table is above 2 inches.
